Containment was a United States policy using military, economic, and diplomatic strategies to temper the spread of Communism, enhance America’s security and influence abroad, and prevent a "domino effect". A component of the Cold War, the policy was a response to a series of moves by the Soviet Union to expand Communist influence in Eastern Europe, China, and Korea. It represented a middle-ground position between appeasement and rollback beginning in 1949.
